FIELD OF THE INVENTION
-
This invention generally relates to an outside handle device and more
particularly to an outside handle device for a vehicle door.
BACKGROUND OF THE INVENTION
-
Recently, an electrically operated door locking device and a wireless remote
control door locking device are employed in a vehicle door so as to enhance
convenience for opening and closing a vehicle door. In an outside handle
device included in such system, electrical components are located and
accommodated in a handle portion assembled at the outside of the vehicle
door. Therefore, the electrical components of the handle portion are
electrically connected to electrical wire of the vehicle body side by using
various manners.
-
For example, a known outside handle device is disclosed in Japanese Patent
Laid-Open Publication published on January 31, 2002 as the publication
number JP2002-30844.
-
In the disclosed outside handle device, the electrical components of the
handle portion are electrically connected to electrical wire of the vehicle body
side via a wire harness (a electrical wire) and a connector.
-
According to the disclosed outside handle, however, when the electrical
components of the handle portion are connected to the wire harness of the
vehicle body side after the handle portion is assembled to the vehicle door,
electrical components of the handle portion have to be connected to the wire
harness of the vehicle body side in a space provided in the vehicle door,
which takes more time to completely assemble the handle portion to the
vehicle door. Especially in such connecting operation between electrical
components of the handle portion and the wire harness of the vehicle body
side, the handle portion is assembled to a predetermined position in the
vehicle door side in advance, so that the handle portion can be assembled to
the predetermined position so as to simplify assembling operation. Further,
the wire harness (electrical wire) has to be provided so as not to interfere with
a door window provided in the vehicle door, then it takes more time to
properly design arrangement of various parts (i.e. the handle portion, door
window) included in the vehicle door.
-
In order to simplify the assembling operation of the handle portion to the door,
a known outside handle device disclosed in European Patent No.
1108835(Fig.2) published on June 20, 2001 includes a handle portion
integrally provided with a connector structure. Consequently, an electrical wire
of a handle side is electrically connected to an electrical wire of the vehicle
body side in response to assembling operation of the handle portion.
-
However when the electrical wire of the handle side is electrically connected
to the electrical wire of the vehicle body side, the handle portion must be a
fixed type. Design allowance in outside handle device is restricted.
-
A need thus exists to provide an outside handle device which can simplify the
assembling operation without design restriction.
SUMMARY OF THE INVENTION
-
According to an aspect of the present invention, an outside handle device
includes a handle portion provided at the outside of a vehicle door and a
handle frame fixed to the vehicle door and supporting the handle portion via
an arm portion provided on the handle portion. The arm portion is provided
with an engaging means and the handle frame is provided with an engaged
means which designates an assembling direction of the arm portion by
engaging with the engaging means.
-
According to another aspect of the present invention, the engaging means
and the engaged means respectively correspond to a protrusion and a groove
which guides the protrusion, and the engaging means and the engaged
means respectively correspond to a groove and a protrusion.
-
According to still another aspect of the present invention, an electrical
component is accommodated in the handle portion. The arm portion is
rotatably provided with a first connecting portion electrically connected to the
electrical component accommodated in the handle portion. The handle frame
is provided with a second connecting portion electrically connected to the first
connecting portion by engaging with the first connecting portion.
-
According to still further aspect of the present invention, the first connecting
portion is provided on the arm portion so as to be surrounded by an internal
surface of the arm portion.

the handle portion 12 is pivotally connected to the handle frame 13 within a
predetermined range.
-
Specifically, the door outer panel 10 has a bended portion 10a curving toward
the inside and handle opening portions 10b and 10c are respectively provided
on the door outer panel 10 at the each side respectively. An arm portion of the
handle portion 12 is inserted in the handle opening portions 10b and 10c (the
left and right sides in Fig3). A handle frame 13 made of resin has an
approximately square shaped inside structure and is formed along the bended
portion 10a of the door outer panel 10. The handle frame 13 is provided with
two frame-side handle opening portions 13a and 13b which are respectively
opened corresponding to the handle opening portions 10b and 10c.The
handle frame 13 is respectively provided with a first internal space S1 and a
second internal space S2 corresponding to the frame-side handle opening
portions13a and 13b respectively.
-
On the other hand, the handle portion 12 includes a handle base 14 and a
handle cover 15. The handle cover 15 is provided on the handle base 14 so
as to cover the handle base 14. The handle base 14 and the handle cover 15
made of resin form an outer shape or profile of the handle portion 12. The
handle cover 15 is provided with a hinge arm (a arm portion) portion15a and a
stroke arm portion 15b at one side (the left side in Fig3, forward of the vehicle)
and the other side (the right side in Fig3, rear of the vehicle) respectively.
-
The hinge arm portion 15a is inserted in the handle opening portion 10b and
the frame-side handle opening portion 13a. A convex portion 15c forming the
edge of the hinge arm portion 15a is in contact with a cover wall portion 13c of
the handle frame 13 including the frame-side handle opening portion 13a. The
handle portion 12 (the handle cover 15) is pivotally connected to the handle
frame 13 with respect to a point where the convex portion 15c is in contact
with the cover wall portion 13c.
-
The stroke arm portion 15b is inserted in the handle opening portion 10c and
the frame-side handle opening portion 13b. A bent portion 15j formed at the
edge of the stroke arm portion 15 is engaged with a known bell crank 16 so
that the stroke arm portion 15b can pivotally rotate within the predetermined
range.
-
As describe above, the handle portion 12 is pivotally connected to the handle
frame 13 with respect to the side of the hinge arm portion 15a (the convex
portion 15c) within the predetermined range which set by the bent portion 15j
is engaged with the bell crank 16.
-
As illustrated in Fig 2, guiding grooves 13h are formed on side wall portions
13d and 13e of the handle frame 13 forming the first internal space S1 (and
the second internal space S2). The guiding grooves 13h are provided along
the assembling direction of the hinge arm portion 15a (the handle portion 12)
so extends along the assembling direction from the frame-side handle
opening portion 13a to the bottom side of the handle frame 13(the bottom in
Fig 1). Then, the guiding grooves 13h are bent in a longitudinal direction of
the side wall portions 13d and 13e. The hinge arm portion 15a includes side
wall portions 15d and 15e extending to the bottom side of the handle frame
13(the lower side in Fig 1). The hinge arm portion portion15a further includes
a cover wall portion 15f. Pair of protrusions 15i is formed on the side wall
portions 15d and 15e respectively and project in opposite directions (the right
and left side in Fig 2). As described later, when the handle portion 12 is
assembled to the handle frame 13, the protrusions 15i are engaged with the
above-described guiding grooves 13h, and then the handle portion 12 is
assembled to a predetermined position along the guiding grooves 13h (that is,
the assembling direction). When the handle portion 12 is located at the
predetermined position, the handle portion 12 is pivotally connected to the
handle frame 13 within the predetermined range.
-
In the handle portion 12, an internal space S3 of the handle portion 12
surrounded by the handle base 14 and the handle cover 15 is provided. In the
internal space S3, a transmitting antenna 21, a door locking sensor 22 and a
door unlocking switch 23 are accommodated. The transmitting antenna 21,
door locking sensor 22 and door unlocking switch 23 are the electric
components for the system which enhances convenience for opening and
closing the vehicle door.
-
The transmitting antenna 21 transmits a certification request signal to a
portable station carried by a user operating the door opening and closing
operation. The door locking sensor 22 detects a variation of capacitance when
the user touches (approaches) the handle portion 12. The door unlocking
switch 23 is a manual switch used for door opening and closing operation.
The door unlocking switch 23 is provided with a switch button 23a and a
detecting portion 23b. The switch button 23a is provided at the handle cover
15. The detecting portion 23b is provided at the handle base 14
corresponding to the switch button 23a. When the switch button 23a is
pushed, the detecting portion 23b outputs a signal. In response to the signal,
a door unlocking operation is performed. Each electrical wire extending from
the transmitting antenna 21, the door unlocking sensor 22 and the door
unlocking switch 23 are connected to an FFC 24(Flexible Flat Cable). The
FFC 24 is led along the hinge arm portion 15a and functions as electrical
wires in the handle portion 12. The FFC 24 is electrically connected to
electrical wires in the vehicle (the handle frame 13).
-
Next, the following description will be given for explaining a manner of
electrical connection between the FFC 24 provided the handle portion 12 and
the electrical wires provided in the vehicle body side (the handle frame 13
side).
-
In the hinge arm portion 15a, a guiding pawls 15g are provided so as to
project in each direction which crosses at right angles as viewed in Fig.1. The
FFC 24 is led to the outside along the hinge arm portion 15a and supported
with both lateral sides being supported by the guiding parts15g.
-
As illustrated in Fig2, a bearing 15h is formed near the protrusions 15i of the
hinge arm portion 15a so as to be extended through the side wall portions 15d
and 15e and a box-shaped connector 17 (first connecting portion) made of
resin is supported by the hinge arm portion 15a. That is, the connector 17 is
integrally provided with a shaft portion 17a which projects corresponding to
the bearing 15h. The shaft portion 17a is inserted in the bearing 15h, and then
the connector 17 is rotatably supported by the hinge arm 15a. In the
connector 17, each wire in FFC 24 is embedded.
-
As illustrated in Fig 1, the connector 17 is assembled to a box-shaped
connector holder 18 (second connecting portion) formed so as to correspond
to the connector 17. The connector holder 18 is provided with terminals which
are electrically connected to each wire embedded in the connector 17. When
the connector 17 is assembled to the connector holder 18, the terminals
provided in the connector holder 18 are surely electrically connected to each
wire embedded in the connector 17. Each terminal provided in the connector
holder 18 is electrically connected to the electrical wire in the vehicle body
side via a cable 19.
-
The connector holder 18 is loosely inserted into a concave portion 13f which
is formed in the handle frame 13 at a wall portion facing to the hinge arm
portion 15a. Accordingly, the connector holder 18 assembled to the connector
17 is provided so as to be pivotally rotatable relative to the handle frame 13
and so as to be pivotally rotatable together with the connector 17 relative to
the hinge arm 15a. Furthermore, the cable 19 is inserted into an insertion hole
13g which extends an approximately central part of the concave portion 13f,
and then connected to each terminal of the connector holder 18.
-
Fig 4 illustrates the handle portion 12 which has been maximally rotated by
external force from a normal state (shown in Fig 1) to a full stroke state within
the predetermined range. In this case, the connector 17 and the connector
holder 18 are pivotally rotatable relative to the handle frame 13, and further
rotatable relative to the hinge arm portion 15a. Therefore, even if the handle
portion 12 is rotated, the connector 17 and the connector holder 18 do not
interfere with the handle frame 13, and then the electrical connection between
the connector 17 and the connector holder 18 is surely maintained. Then, the
electrical connection between the FFC 24 in the handle side and the cable 19
in the vehicle body side is surely maintained via the connector 17 and the
connector holder 18. When the handle portion 12 is returned from the full
stroke state to the normal state (shown in Fig.1) after the external force
released, the electrical connection is surely maintained as it with the foregoing
case.
-
Fig.5 to 8 illustrates an assembling process in which the handle portion 12 is
inserted into the handle frame 13. As illustrated Fig 5, initially, the connector
holder 18 is temporarily assembled to a predetermined position so as to be
loosely inserted in the concave portion 13f. The connector 17 is temporarily
assembled to a predetermined position so that the front edge of the hinge arm
15a can project from the front edge of the hinge arm 15a. In this case, the
connector 17 is supported by the connector holder 18 with a frictional force
between the connector 17 and the connector holder 18. Then, in the frame-side
handle opening portion 13a, the protrusions 15i of the hinge arm portion
15a are set to the guiding grooves 13h. The protrusions 15i of the hinge arm
portion 15a are inserted in the frame-side handle opening portion 13a so that
the protrusions 15i of the hinge arm 15 can engage with the guiding grooves
13h of the handle frame 13.
-
Next, as illustrated in Fig6, the handle portion 12 is moved to a bended edge
of the guiding grooves 13h via the protrusions 15i. By this movement, the
hinge arm portion 15a is inserted in the handle frame 13 from the handle
opening portion 10b and the frame-side handle opening portion 13a (see
Fig.1). Under this condition, the stroke arm portion 15b is inserted in the
handle frame 13 from the handle opening portion 10c and the frame-side
handle inserting portion 13b (see Fig.3). When the handle portion 12 is further
moved along the guiding grooves 13h as illustrated in Fig 7, the protrusions
15i are displaced at the rear anchor of the guiding grooves 13h bending in a
longitudinal direction of the side wall portions 13d and 13e (forward of the
vehicle). In this case, the connector 17 is moved relative to the connector
holder 18 so as to concentrically face toward the connector holder 18. As
illustrated in Fig 8, the handle portion 12 is further moved along the guiding
grooves 13h via the protrusions 15i. The hinge arm portion 15a is further
inserted toward the cover wall portion 13c. In this case, since the connector
holder 18 is provided in the concave portion 13f, axial movement of the
connector holder 18 is restricted, and then the connector 17 concentrically
provided relative to the connector holder 18 is surely and electrically
connected with the connector holder 18. That is, the handle portion 12 is
guided via the guiding grooves 13h and the protrusions 15i engaged with the
guiding grooves 13g, after the hinge arm portion 15a(the stroke arm portion
15b) is inserted in the handle frame 13 via the frame-side handle opening
portion 13a, the hinge arm 15a is finally assembled along a direction in which
the connector 17 is engaged with the connector 18.
-
As described above, the following advantages will be given according to the
embodiment of the present invention.
-
According to the embodiment of the present invention, when the handle
portion 12 supports the handle frame 13, the assembling direction along
which the handle portion 12 is assembled to the handle frame 13 is provided
by the guiding grooves 13h and the protrusions 15i engaged with the guiding
grooves 13h. Thus the handle portion 12 is smoothly set to be supported by
the handle frame 13 at the predetermined position along the assembling
direction. The handle portion 12 can be provided and supported at the
predetermined position, and then a design allowance of the handle portion 12
can be improved regardless of the handle type. Furthermore, a misalignment
of the handle portion 12 relative to the predetermined position can be reduced
by assembling the hinge arm portion 15a to the handle frame 13 along the
assembling direction of the hinge arm portion 15a. Accordingly, looseness
and twist generated by the misalignment can be reduced, and operation
feeling can be improved.
-
According to the embodiment of the present invention, the assembling
direction of the hinge arm 15a is designated by simple structure forming by
the guiding grooves 13h and the protrusions 15i.
-
According to the embodiment of the present invention, the connector 17 can
be smoothly and electrically connected to the connector holder 18 by
assembling the hinge arm portion 15a to the handle frame 13 along the
assembling direction. The connector 17 is connected to the hinge arm portion
15a so as to be pivotally movable relative to the hinge arm 15a. In other
words, the connector 17 is rotatably supported by the side wall portions 15a
and 15e of the hinge arm portion 15a. Thus, the connector 17 is electrically
connected to the connector holder 18 so that manufacturing difference and
assembling difference can be absorbed. Especially, even if the assembling
direction of the hinge arm 15a mainly consists of two directions as described
in the embodiment, the hinge arm 15a is assembled along the assembling
direction without problems, and then the connector 17 is surely and
electrically connected to the connector holder 18. The connector 17 is
inserted and electrically connected to the connector holder 18 surely.
-
According to the embodiment of the present invention, the connector 17 is
surrounded by the hinge arm 15a via the internal surface which is formed by
the side wall portions 15d, 15e and cover wall portion 15f, and the shaft
portion 17a corresponding to rotational axis is provided within the internal
surface so as not to project to the outside of the hinge arm 15a. Thus, for
example, when the hinge arm portion 15a is assembled to the handle frame
13, the connector 17 does not interfere with other members (the outer panel
10 and all), and electrical performance of the connector 17 can be maintained.
-
Additionally, an embodiment of the present invention is not limited to above-described
preferred embodiment. The following change may be applied.
According to the above-described embodiment, the hinge arm 15a includes
the protrusions 15i and the handle frame 13 includes the guiding grooves 13h.
However the hinge arm portion 15a may include a guiding grooves portion (an
engaged means) and the handle frame 13 may include a protrusions portion
(an engaging means).
-
In the above-described embodiment, electrical components accommodated in
the handle portion may be changed in response to a door opening and closing
function. That is, the electrical components may be changed in response to a
system provided in the vehicle door (an E-Latch System and Smart Entry
System).
-
Alternatively, the outside handle device may include the handle portion in
which electrical component is not accommodated.
According to the above-described embodiment, a fixed type of handle portion
is employed in the outside handle. However, an unfixed type of handle portion
may be employed in the outside handle.
-
The principles, preferred embodiments and mode of operation of the present
invention have been described in the foregoing specification. However, the
invention which is intended to be protected is not to be construed as limited to
the particular embodiments disclosed. Further, the embodiments described
herein is to be regarded as illustrative rather than restrictive. Variations and
changes may be made by others, and equivalents employed, without
departing form the spirit of the present invention. Accordingly, it is expressly
intended that all such variations, changes and equivalents which fall within the
spirit and scope of the present invention as defined in the claims, be
embraced thereby.
-
An outside handle device includes a handle portion provided at the outside of
a vehicle door, a handle frame fixed to the vehicle door and supporting the
handle portion via an arm portion provided on the handle portion. The arm
portion is provided with an engaging means, and the handle frame is provided
with an engaged means which designates an assembling direction of the arm
portion by engaging with the engaging means.
